Code review comment for lp:~raof/mir/no-ipc-on-compositor-threads

system_executor() is named as such in honour of the C++ TS. I guess it shouldn't really be named that :)

This shouldn't be a problem for multiple servers in a single process - they'll all use the same IPC thread for buffer-return messages, but each buffer-return task should be extremely quick - almost just a syscall - and there shouldn't be all that many of them - they'll generally max out at 60/s/client.

If you run *lots* of really busy servers in the same process that might start getting awkward.
